Extending its losing streak, the BSE Sensex today declined over 53 points in early trade on sustained selling by funds after weak cues from CPI and IIP data.

The retail inflation measured in terms of consumer price index (CPI) rose to 10.09 per cent in October, entering double digits after seven months. Meanwhile, industrial production grew by two per cent in September, mainly on account of better performance by power and mining sectors.

The 30-share index fell by 53.97 points, or 0.27 per cent, to 20,227.94 in first five minutes of trading. The BSE Sensex lost 957.45 points in past six sessions.
